I made the above comment earlier today, as a joke, in reference to flickr's fickle explore feature. Currently yours truly has a photo up, somewhere, in the Last 7 Days section:
I know it's there because the stats say so, though I haven't found it myself. This is, of course, very cool, and I appreciate the increased traffic and commentary from where ever it comes. Still, I've come to realize over the years how completely random and arbitrary this stuff can be. Sure, it helps when you have a good photograph, as I often do, but I've had quite a few excellent shots go uncommented entirely. What the gods of flickr giveth, they taketh away. I find it's best to just keep shooting and not worry about it.
Photo details: Nikon D7000 with 16-85mm lens, 1/320sec at f4.5, ISO200. This was shot the morning after our first big snow storm of the year.
